Rendition is supposed to be sending the winner(s) to E3 which takes place at the end of May. So you probably have less than three months to finish.
Anyway, to do antialiasing on the Verite, you first have to draw the adjoining triangles, then you tell the Verite to antialias the edges. (It actually just sort of "blurs" the pixels together with a bilinear filter.) You might be able to draw the whole scene first, keeping a list of all the edges, then at the end do all the antialiasing at once.
It is most important that you smooth the outside edges of the objects. You only have to bother with the inside edges if there is a big change in textures or something.
I wrote a little howto: a few articles down. You should read that for some of the actual programming you need to do. You have to put the Verite into a very specific state before edge antialiasing will work. Then set it back at the end. This slows down performance, which is why you should try to do all the antialiasing at once.
And good luck!
